Last night there was a festival of light (called Lichterfest in German) being put on here in Stuttgart. I didn't have any other plans, so I had decided to go there with my flatmates. The family of one of my flatmates was also visiting, so there were a party of us going.
We arrived just before the fireworks were to be set off, and had a chance to see some of the lanterns that were being carried around by visitors, and that were hung up around the park. The Killesbergturm had been lit up as well, giving a sort of focal point to the park. Soon, the fireworks were being set off in time to the music (sort of) and everybody was ooh-ing and ah-ing.
It brought back some nice memories of one of the first times (if not the first) that I had visited Switzerland when I was younger, and had a chance to go to a similar festival there. There are some photos on Flickr from last night's event, though I didn't actually get around to taking any myself.
